Managing malignant sublingual gland tumors: a single institution experience with 23 patients.
Article in BMC cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDue to the relative rarity of malignant sublingual gland tumors, diagnosing and treating them clinically pose challenges. Hence, there's a need to explore the pathological types, characteristics, treatment methods, and prognosis of primary malignant tumors of the sublingual gland to improve our understanding and management of these rare yet highly malignant conditions.
methodsThis study reviewed cases of primary malignant sublingual gland tumors, analyzing their characteristics. The treatment methods included surgical excision, with additional radiotherapy, or brachytherapy for advanced stages or positive surgical margins. The study also summarized different treatment approaches, including lymph node dissection and soft tissue reconstruction using free flaps such as the anterolateral thigh flap and forearm flap.
resultsWe have gathered 23 cases of sublingual gland malignancies treated at the Department of Oral and Maxillofacial Surgery, School and Hospital of Stomatology, Wuhan University, from January 2013 to May 2024. The most common pathological types were adenoid cystic carcinoma and mucoepidermoid carcinoma, with rare cases of mucosa-associated lymphoid tissue (MALT) lymphoma and nonspecific salivary gland clear cell carcinoma. Early diagnosis and surgical intervention were crucial for a favorable prognosis. Marginal mandibulectomy was necessary for cases involving the mandible. Patients with positive preoperative lymph node detection required cervical lymph node dissection. Extensive tissue defects in the floor of the mouth were effectively reconstructed with free flaps to prevent oral-mandibular fistula.
conclusionSurgical excision remains the preferred treatment for malignant sublingual gland tumors. Early diagnosis and comprehensive surgical management are essential for improving prognosis. The study's limitations include a small sample size and short follow-up duration, necessitating further research with larger clinical samples to confirm these findings.
